Inspection in the camera, in grey levels
A smart camera combines the sensor, the processor and the inspection software in one housing and reports a result to the line controller. Most presence, position, measurement and code tasks work on brightness contrast, which a monochrome sensor captures with more signal per pixel than a colour sensor of the same size.
- Check that the task needs no colour decision; choose the light colour for the best contrast on the part instead.
- Work out the resolution from the field of view and the smallest feature, and check the lens and built-in light of the selected model.
- Confirm the vision tools included, the industrial protocols and I/O, and how the camera is triggered and powered.
